UPJ1K470MPD

The UPJ1K470MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, offering 47 µF capacitance at an 80 V rating with polarized construction. Designed for general-purpose power applications, the UPJ series is specified for low impedance and high reliability and is particularly suited to switching power supply circuits.

This compact φ8 × 15 mm can delivers stable performance across a wide temperature range (−55 °C to 105 °C) and is offered in bulk/bag packing for production use.

Key Features

• Rated Capacitance & Voltage: 47 µF nominal capacitance with an 80 V rated voltage for higher-voltage power rails.
• Capacitance Tolerance: ±20% measured at 120 Hz, 20 °C, enabling predictable filtering and energy storage behavior.
• Low Loss Tangent: tanδ up to 0.08 per datasheet specification for the 63–100 V range, supporting efficient AC ripple handling.
• Ripple Current Capability: Low-frequency ripple current of 89.25 mA (120 Hz) and high-frequency ripple current of 175 mA (200 kHz), suitable for typical switching regulator environments.
• Leakage Current: Specified leakage current of 112.8 µA after application of rated voltage, aiding predictable standby and bias conditions.
• Endurance: Rated life of 3000 hours at 105 °C for the φ8 size, with post-test limits on capacitance change, tanδ, and leakage per datasheet endurance criteria.
• Packaging & Mounting: Radial lead package (lead spacing 3.5 mm, lead spacing tolerance ±0.5 mm) in bulk/no terminal forming or bag packing for flexible assembly workflows.
• Environmental Compliance: RoHS compliant per the product data.

Typical Applications

• Switching Power Supplies — Suited for bulk filtering and output smoothing where the UPJ series is specified for low impedance and switching environments.
• General-Purpose Power Electronics — Useful where a polarized 47 µF, 80 V capacitor is required for energy storage or decoupling on higher-voltage rails.
• Compact Radial Installations — The φ8 × 15 mm can and radial lead format suit tight board layouts and through-hole assembly processes.

Unique Advantages

• High-Voltage Capability: 80 V rating provides margin for higher-voltage rails and designs that require elevated DC bus voltages.
• Design Predictability: Specified capacitance tolerance, tanδ, leakage current, and ripple current values allow accurate thermal and electrical planning.
• Temperature Endurance: Rated to operate from −55 °C to 105 °C with a defined 3000-hour endurance at 105 °C for the φ8 case, enabling deployment in demanding thermal environments.
• Radial Through-Hole Form Factor: Standard lead spacing and radial can package simplify replacement, prototyping, and legacy board integration.
• Production-Ready Packaging: Available in bulk or bag packing to support prototyping through mass production workflows.
• Regulatory Compliance: RoHS compliance supports use in markets and products requiring restricted substances conformance.
